CarTrain "Sensors, open- and closed-loop control systems"
The subject of sensors is already a core subject of training in the area of service, repairs and diagnostics. The sensors in the motor vehicle are digitally networked and in recent years have taken on ever greater importance. The number of sensors inside the motor vehicle has also increased dramatically. How sensor signals are evaluated is also becoming more and more important in practical everyday diagnostics. The way sensors and actuators interact via open- and closed-loop controlled systems has also continued to become more complex. In this training system signals are recorded and evaluated using hands-on measuring and testing methods. Faults and malfunctions are diagnosed on vehicles based on customer complaints and by applying hands-on methods working with circuit diagrams and function diagrams. Measurements are performed using the integrated measurement interface and with the aid of all other suitable measuring instrument found in the repair shop.
